Hi, I just received a new package of the Bergger Print Film and I read the spec sheet which does not supply any information on a starting development time for the film. The spec sheet only shows a CI curve which has a range of 1.0 to 2.0 and dev times ranging from 4 min to 16 min using D76 stock at 22C. This is confusing to me because I thought a normal CI for making silver gelatin prints was in the .5 range and .7 range for platinum for example. I am sure I probably just don't fully understand the chart I am looking at.
I am looking for help on how I can properly test and establish a standard development time with this print film.
Can someone here outline the steps I need to take in order to do this properly?
I have included a photo of the CI curve mentioned above.
